While the adsorptions of 1-propanol and 1-Br-propane at 100℃ give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 ℃ shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150℃, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO〓 catalyst.

While the adsorptions of l-propanol and 1-Br-propane at 100 癈 give rise to 1-propoxy species, which mainly converted to propanal at higher temperature. IR spectrum arising from the interaction of propene with the catalyst at 100 癈 shows the IR bands of allyl alcoholate and isopropoxy species. As the temperature was increased to 150 癈, the bands ascribable to the adsorbed acetone and acrolein were observed. Based on these results, it is suggested that isopropoxy species is one of the intermediates for SOP to acrolein over MoPO/SiO2 catalyst.

The thermodynamic investigation of adsorptions shows that adsorption of CCTS to Pb~(2+),Cu~(2+),Cd~(2+),Ni~(2+) is spontaneous.Because the values of Gibbs free energy are negative and the calculated entropy values of interactions are positive.However the positive values of the variation in enthalpy show that besides chemisorption, other processes of decalescence, such as physical adsorption and swelling of CCTS were also involved.
CCTS对各重金属离子的吸附热力学分析结果表明:CCTS对各重金属离子吸附熵变△adsS为正值,并且吸附自由能改变量△adsG均为负值,说明CCTS对各重金属离子的吸附是自发进行的,但其吸附焓变△adsH为正值,说明CCTS对重金属离子的吸附不仅仅是化学吸附的过程,还伴随着其他如物理吸附、吸附剂溶胀等吸热过程。

The results show that the maximum growth quantity of Nocardia can be achieved after culturing 120 h and obvious selective adsorption of Nocardia on the surface of pyrite and sphalerite can be detected. The maximum adsorption rate on the surface of pyrite is 96.99%, whereas it is less than 20% in the case of sphalerite. Adsorption equilibrium can be attained within 20 min on the surfaces of the two minerals. pH value is the key factor influencing upon selective adsorption, and the difference of adsorption quantity on the surfaces of two minerals is apparent when pH is between 4 and 10. Slurry concentration over 6 g/L is favorable to selective adsorption. Nocardia cell concentration, stirring speed and temperature have no obviously effect on selective adsorption.
